Kit 50cc high engine Ø39.9mm AIRSAL luxury cast iron bi-segment DERBI euro 1 and 2

Here is the brand new 50cc kit from AIRSAL. For the first time AIRSAL is launching into cast iron kits. You should know that a cast iron kit is more solid on long journeys, so it allows additional reliability but it gives a little less power than an aluminum kit. This model has not Ø39,9mm diameter do not hide, good performance in comparison to the original.

It will certainly be more efficient because it has a very correct finish, work in the channels reviewed and corrected but is above all a good element to start again on a good basis. It is of course equipped with a two-segment piston for better torque and sweeping.

In addition it is sold with an aluminum cylinder head for better heat dispersion. Clearly it is a very good kit, better than the original which will give you reliability and torque without spending too much.

The pack contains :
Complete seal pack
Cast iron cylinder 5 transfers
Bi-segment piston
2 segment
High compression cylinder head
2 piston clips

Piston pin Ø12mm

As an option we offer a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
